Oneach side of the center bar 13 is attached a bar, 0, by means of loops 0a, or other suitable means, which will allow said side bars to turnfreely up or'down. From the outer side of each bar 0 project three par--allel bars, D D, set at an angle with the bar 0, as shown, and connectedon their under sides by a brace, E, which is also secured on the underside of the bar -G,.-and projects beyond the same so as to overlap theedge of the center bar B,and form a stop, e, for the downward movementof the bars G and D.

These bars or stops are so arranged that the two harrows can turn downonly a certaindistance below the horizontal plane of the center beam B.In the bars 0 and D are inserted rake-teeth b b, of any ordinary form,thus making, in fact, two separate and independent bar B is slightlycurved infront ate, and the I wings, when raised, throw the bar B uponthe ground, thus forming a runner.
